Year 423 (CDXXIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known in Rome as the Year of the Consulship of Marinianus and Asclepiodotus (or, less frequently, year 1176 Ab urbe condita). The denomination 423 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
